Advantages and Techniques of Utilizing Anterolateral Portal in Delaminated Rotator Cuff Repair

Typically, rotator cuff repair is performed two-dimensionally while visualizing the subacromial space. To achieve a more complete repair, sutures can be retrieved from inside the joint utilizing a penetrating suture device through the anterolateral portal, which permits visualization of the articular side and bursal side of the rotator cuff tear. Utilizing other portals can leave the sutures out of sight and reach. The anterolateral portal helps capture both leaves of a delaminated tear and places the sutures in the center of the field for retrieval and tying. The anterolateral portal is located with a spinal needle just off the anterolateral corner of the acromion, and the suture anchor is inserted into the greater tuberosity through this portal. The sutures are passed into the joint through the tear in the rotator cuff with a suture grasper. The scope is redirected intraarticularly, and the suture is visualized. The sutures are positioned, and the penetrator is passed through the tendon. The scope is placed back in the bursa for tying sutures and capturing both leaves of a delaminated tear. It works equally well for simple complete tears and partial articular-sided supraspinatus tendon avulsion lesions.
